1.1 What is implied when the current direction is based on the electron theory? When it is based on the generally adopted practice or the conventional way? 1.2 List and discuss the important elements of an electric circuit. 1.3 Why is it sometimes fatal to touch the wires in an electric power line and not nearly so dangerous to come into contact with an electrostatic machine that is developing a much higher voltage? Can one be "shocked" by touching a wire carrying a very large current in an automobile starting system? Why? Why are birds not injured by sitting upon a high-potential power line?
